PPS Fiber for High-Temperature Filter Media
PPS fiber combines excellent chemical resistance, hydrolysis stability, and high-temperature endurance, making it an ideal material for industrial filter felts in power plants, cement, and waste incineration.
Description
PPS (Polyphenylene Sulfide) fiber is one of the most widely used high-performance fibers in industrial filtration. Its semi-crystalline structure provides exceptional resistance to acid, alkali, and oxidizing gases, while maintaining strength and dimensional stability at elevated temperatures.
Compared with polyester and aramid fibers, PPS fiber offers superior chemical durability, ensuring long service life in coal-fired boilers, cement kilns, and chemical industries where moisture and acidic gases are present. This makes PPS filter media a cost-effective solution for industries balancing performance and operating cost.
